JACOB WEIDENMANN, OF NEW YORK, N. Y.

BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 253,901, dated Februaiy 21, 1882.

Application filed March 3, 1881. (No model.)

To all whom it may concern:

Be it known that I, JACOB WEIDENMANN, a citizen of the United States, residing at New York, county and State of New'York, have invented a new and useful Button-Fastening, of which the following is a specification.

My invention relates to improvements in self-fastening buttons; and the objects of my improvements are to provide a cheap, easilyadjustable, and secure fastening for buttons and analogous articles, such as badges, &c. I attain these objects by the device illustrated in the accompanying-drawings, in which the different figures show different forms of my invention.

Similar letters refer to similar parts throughout the several figures and views.

The button may be made of metal, bone, horn, celluloid, or other substance, and it may be covered with a textile fabric or not, as desired.

The drawings show the device applied to uncovered buttons, Figure 1 illustrating the simplest form of my fastening, Fig. 2 a stronger form, and Fig. 3 the under side of a button provided with my device.

Fig. 1 shows a top view and two side views of a button provided with my fastening. A represents the face or body of the button, which has or may have some ornamental device on its face, and when the latter is the case one part of the ornamental figure is mounted upon the lever d, hinged to the button at b, and lying flat upon the surface of the button. Attached'to the under side of the l ever (1, and passing through a hole in the button, is the curved spur or tooth c. This spur or tooth is curved in form, and should be long enough to take a firm hold of the cloth, and it is better that its point should come in contact with the under surface of the button, thus removing danger of pricking the fingers in using the button and securing a firmer attachment. When the lever d is raised the point of the spur c is elevated, and the button is then placed in position upon the cloth and the lever depressed, the spur passing through the cloth, and when the lever d is flat upon the surface of the button the spur fastens the button to the cloth. This form of fastening is sufficiently secure for buttons or other attachments which have onlya slight strain to bear.

Fig. 2 illustrates a button which has a Fig. 3 shows the under side of buttons provided with one, two, or more stationary spurs and corresponding movable spurs mounted on hinged levers, according to the strength of fastening required.

It is evident that these are all obvious modifications of my device, and the adoption of either form will depend upon the strength of fastening required.

.I am aware that buttons have been made with curved teeth to fasten them to the fabric, such a fastening being described in the United States patent to Alexander and Breed, of March 13, 1877, No. 188,327; but such teeth are immovable, and are open to the objection that they can only be made with their points running in the same direction, which allows the button to move from side to side, while at the same time they are less easily adjusted than my fastening. From the use of my hinged lever I can make the teeth cross each other at right angles, thus making the buttons immovable and very secure.

What I claim is-- v 1. A button provided with a fastening device consisting of one or more hinged levers bearing one onmore curved teeth, the levers being operated from the upper side of the button, and the teeth passing through holes in the button and adapted to pierce into and JACOB WEIDE NMANN.
